Packaging and application device for cosmetic product
A recently granted patent (Publication Number: US11737547B2) describes a packaging and application device for a cosmetic product. The device includes a mechanism that receives a stick of cosmetic product and allows for the movement of a cup within a tube, enabling the application of the product. The device consists of a base, a tube, and a cup, with the cup being movable between a retracted position for packaging and an extended position for application.
The device also includes a base cover that houses a portion of the mechanism and a cap that is fixed onto the base cover to create a second housing for another portion of the mechanism. The base cover and cap are linked in a seal-tight manner to ensure product integrity. Seals are inserted between various elements of the base cover, cap, and mechanism to provide additional protection against leakage.
The patent also describes the construction of the base cover, which includes a base cladding shell and a ferrule fixed onto it. A base insert may also be included. The seals may be overmolded onto the base insert or clamped against the ferrule or mechanism element.
The cap consists of a cover and a cap insert that defines the second housing. A cap embellisher may also be included. The seals may be overmolded onto the cap insert or inserted between the cap embellisher and the mechanism element.
The patent further details that the seals used in the device may be made of materials such as Hytrel® and Arnitel®. These seals may be domed toward the mechanism to enhance their sealing capabilities.
Additionally, the device has an air passage that allows for airflow between the first and second housings when the cap is fixed to the base cover. The cup, which has a cylindrical shape, is open at both ends and emerges into both housings.
The patent also includes a separate claim for the mechanism itself, which features a base, tube, and cup. The cup has relief sections that complement a helical groove in the base, allowing for the movement of the cup when the tube is pivoted. The mechanism also includes an air passage that connects two orifices within it.
Overall, this patent describes a packaging and application device for cosmetic products that ensures product integrity and provides a convenient and efficient way to apply the product.
